Abstract:
We present the results of 22GHz H2O maser observations of a sample of
85 post-asymptotic giant branch (post-AGB) candidate stars, selected
on the basis of their OH 1612MHz maser and far-infrared properties.
All sources were observed with the Tidbinbilla 70m radio telescope,
and 21 detections were made; 86GHz SiO Mopra observations of a subset
of the sample are also presented.
Description:
For the OH observations, a complete sample of 88 sources was selected
from the ATCA/VLA survey as likely post-AGB sources on the basis of
their IRAS and MSX far-infrared colors. The 22GHz observations for
all 85 sources were taken as service observations with the Tidbinbilla
70m radio telescope between 2003 April and 2004 May.

dNNN = SCHD NNN
bNNN = SCHB NNN
vNNN = [SVM2001b] NNN
Note (2): MSX class codes is as follows:
Q I = MSX quadrant I (older post-AGB stars)
Q IV = MSX quadrant IV (young post-AGB stars)
Note (3): IRAS class code is as follows:
LI = IRAS LI region (more massive post-AGB stars)
RI = IRAS RI region (less massive post-AGB stars)
